'jBe itknown that I,AMBnos 1p,s a `citizen of the UnitedStates, residingin the borough ofBrooklyn, 'city andQState of New York, haveinventedneyvr andusefnl Improvements .inA Calculating-Machines, of whichthe following is a specification. f

More particularly, this invention relates to improved andsimplifiedycarria e-oontrolled machine-actuated counter-se ecting meansfor a multiple counter.machne,said means being rendered operativeorinoperative atwll. 1"

Multiplecounter machines at once sggest means to select for operation,one or another set of normally idle counters, or vice versa, toselectively retain one" or another set of normally operablecounters,vout of operative position. i' i At first, this selection wasmanually efected by means of a lever, ke s, or other devices, pressureon which shi ed the 4desired counter tocii'ective position." f .Fromthis beginning, the art developed along two lines. In one, the papercarriage, as it shifted from column to column in tabulating or shuttlingoperations, effected the necessary adjustment of the parts to select thedesired counter on which accumulations were to be made, the other linecomprising l thosedevices wherein the operation o'f the machine itselfwas relied upon to furnish the powerto shift the counter-selectingmechanism in accordance with the desired system or method employed b theoperator. In other words, the art eveloped carriage-drivencounter-selecting mechanisms, and machine-driven counter-selectingmechanisms.l Y 1 Later, the two lines merged in a ty e of device'embodying a carriage control o machine-actuated counter-selectingmechanism to which my invention relates.

One object of the present invention is-to provide a simplified form ofautomatic carriage-controlled, machine-driven counterselectingmechanism, which embodies a novel principle of operation, and possessesadYantages not found in prior constructions for accomplishinor the sameresult.

Pursuant thereto, I provide the counterselecting means shown in thepending a lication of Pentecost and Fisher, filed uly 17, 1918,SeriaLNo. 245,273, with transmitting means, adjustable by the carriagein its 1i: i :'-fvx- 'u H'. travel past the printn point,'fre,lativelyto a drivemeans lactuated om themhinshaft of the machineif `To enablethe operator to determine when this drive means shall becomeactive andwhen itshallv remain idle, I have contrived an, actuating .mechanismoperated from the lmain shaft, and have arranged a manuallycontrolledcoupler, shiftable to or disconnect the ,actuating mechanismv andthedrlvemeans'. fj.; v, f

In the accompanying drawings, Figure 1 is a view in slde` elevation of amulti le counter machine of the well-known Wa es type, equipped with oneembodiment of my invention, tie carriage-controlled, `machinedrivencounter-selecting mechanlsm bein disconnected, and the machine at rest,wit

The platen is supported on a shaft 2004 journaled in end frames2010"secured to a slide 2065 shiftably mounted between ways 2067. andforming acarriage, theadiustl A 2067 enables the operator to print inany desired column on the paper.

A clearing; keyvv 327 and a total key 327 (not shown) to'vary the timeof engagementand disengagement of andl racks. in the 'usual manner` toeffect total printing, and to clear the machine, respectively.

To select which set of numeral wheels or counters shall become active`and to retain the remaining set or sets of counters inactive* there havebeen provided counter-selectinn' cross heads 418'" mounted on the upperends of levers 418 fastened near the opposite ends of a suitablyiournaled cross shaft 402. The cross heads 418m are of'suiiicient widthto extend beneath both axles 400 of the two sets of counters hereinshown for illustration, when the levers are in their 'tion,' a linkintermediate; positions, andare preferably slotted, asf: at 418f,"toembrace the opposite ends oi'the. axle of one Aor the other set ofcounterswhen the headsiaretshifted to either side ofI vtheiriinteriiediateyy positions, to therebyfloek such 'set' oficounters outof operation.

Y r`Manualfcounter-'seleotox'n is leffected b the adjustment of afhandle 1118"Awhich ,may be connected to onelof the heads 418m.

An interlocking mechanism I' is .provided to prevent atteniptstorchanfthe counterselection adjustment; after -t e main drive shaft 200 hasstarted on its forward@ stroke1 and further, to prevent'an operation -ofthe main drive V"shaft lwhen the counter-selecting headsare not locatedin one oranother of their adiuS iPositions; ".fn: Considering-wrst the'g means ftvhich .preventsl-y an attempt* to lth'e' -.maiir drive shaft200 'on fits-:forward stroke during `an adjustment of thetcounter-'selecting Lmechanism, and when the counter-selecting mechanism`is 1 not rin "fa 'properly' 'adjusted posi- 421" l(lipgssl and 2)conveniently secured' to one of the counter-selecting heads 418,connects" the counter-selecting mechanism with a swinging control late-421l which may bejournaled on one "o the well-known removablethrough-'rods 102 used in the Wales machine to secure the keyboard inplace." A stud354 projecting;` inwardly from the `control plate 4521*,lies to one side or another of eithenOf a pair of abrupt cams 422'. 422carried: on the rearwardlyiextending army of a lever 422 fast on theinner end of a stub shaft 457dmounted in one of the usual side frames.A' spring 388D presses the rearwardly extending arm of the lever"422upwardly against the stud 354. As' seen in Fig. 1, when thecounterselecting mechanism 4is in its intermediate position, in which itholds-@both sets oi counters 490, 4:901t out of engagement with theracks 410, the stud 354;z lies in the rccess between the two cams 422W,422". l Shifting the couliter-selectinar mechanism 1to one or the otherof its extreme positions. `actuates the link 421" to' swing the controlplato 421 in one direction or the other, and thereby wipe the stud 354'over one or the other of the cams 422', 4221' until it lies on thcopposite side thereof (see Fig. 2).

The stud, as it Wipes over the sharp cam rises. depresses the rear' armot the lever 422 bearing such cams. against the tension of the restoringspring 388". not only elevates the forward arm of the lover. but alsoturns the stub shaft 457".

A link 423b connects the forward arm of the lever 422 fwith the tail Vofa dog 123 journaled on a guidehpin 954", and a spring 486 (Fig. 2)inferior to the sprin 388", tends to engagethe tooth 423in of the og 423with the notrhes'in the usual full'strolre segment 210r fastened to,-and turning with, the main dri-ve shaft 200.

Normally :the =spring1388p retains the for- Ward arm of the lever 422andthe'linl: 423" .in their lowered positions, to `'hold the dog $23inidleposition, 'but when thea-forward arm of lever 422 rises,'iitxzroleases the link 423" fand-'dress thel :dog ato `the Aactionv Tof`itsSpring .486,which thereuponsnaps the dog into engagement with the fullstroke segment 21() to lock `the main drive shai't against rotationduring .theadjustment of the counter-selecting mechanism.

As' the 'counter f- Selecting mechanism reaches oneor another-.of itspredetermined positions, ythe stud 354z rides oli' of the cam 422m or422", to release the tlever 122 and stub shaft 45T* to the action of thelspringI 388, which thereupon restores the lever to normal position: andlowers the forward arm and link 23h10 disengage the paivl 423 from thefull stroke segment 210r against the tension of the lighter spring 486".y

To enable the locking dog 423 and link 4:23b to be operatedindependently of 'the lever 122, I provide a pin and slot conne@ t1on350m between the lever and the'llnk 42. b.

In motor-driven machines, it is connnon to start the machine by simplytouching a key, as fully set forth in U. S. Patents to Kntzler,1,080,515, December 2, 1913 and 1,151,803, August 31, 1915; Hunter andKntzler, 1,093,424, April 14. 1914: and 1Wilgus, 1,150,910, August 24,1915, to which reference is made for a more comprehensive understandingthereof.

When machines are adapted for both manual and motor operation, it iscustomary to remove the handle -by which the manual operation iseffected, when the machine is-to be motor-operated, and to apply thehandleA when the machine is to be manually-operated. It has been foundadvisable to ar range that 'the removal of the handle from the machineshall render lthe full stroke segrment ineffective, and that theapplication of the handle shall render the full stroke sen'- menteifeetive, as set 'forth for example in S. Patent to lx'intzler.1,074,054, Septomber 23, 11913. Hence, the counter-selectionmechanism-controlled dog` 423 operable upon theifull stroke segment willbe ineffective to prevent the operation of the machine by the motorduring an adjustment of the counter-selecting mechanism, and when thecounter-selecting mechanism is left in an improper position.

' Reference is 'directed to the above-mentioned pending applications ofPentecost and Fisher for a more comprehensive understanding of theforegoing, which constitutes a part of the present invention only in sofar as itis combined with the novel features hereinafter explained.

In the commercial operation of calculating machines, it is frequentlydesired to print a series of items across a sheet, some of which itemsit is desired to accumulate in one or another set of counters, andothers of whichv are to be printed only. l -1 -To render unnecessary themanual shifting of the counter-selecting mechanism, and to enable theuser tol perform his work in a shorter periodof time, as Well as toeliminate the necessity for charging his mind with lthe manual selectionof the proper set of counters' at the proper time, I havearranged asimple and novel means controlled by the carriage to automaticallyeffect the selection of the proper set of counters on' which torelegsterv the items. Thus the carriagre` as it` shifts ,to the columnin which it is desired to print an item. will set mechanism which, uponthe operation of the main drive shaft, will automatically select the setof counters in which it is desired to accumulate such item.`

A washer or head 1614 on theouter end of the stud overlies the outer face of the lever and coperateswith the collar adjacent the inner face of the lever, to guide thelatter in its travel relatively to the rocker, and to retain the lever.at a' constant distance therefrom. i

The slot 4G19y is made widerthan the diameter of the stud 250b tocompensate for the different arcs of travel of the rocker 220 and lever4191, respectively, due to the difference in centers.

A carrier 4195 pivotally'secured at 257, to the head ofthe actuatinglever 4193, extends rearwardly alongside the inner face of the lever,and supports a cam block 419 at its free end. YA pin 353t mounted in thecarrier', passes 'through a slot 419 in the head of the actuating lever4195, and a spring 480 connected `to the protruding end of the pin andto the lever 4195, normally holds the pin 353' at the-lower `end of Yitsslot,.to yieldingly yretain the cam 419" in them. path of a wiper 354'Jprojecting from the adjacent radius bar 323.

As the radius ybars 323 advance on the forward stroke of the main driveshaft (Fig. 2), the wiper 354b strikes the opposing upwardl inclined camface of the block 419, an proceeds to ride therealong. As the pin 353tis at the lower end of its slot 419, the carrier 419 cannot yieldrelatively to the actuatin lever 419l and consequently the pressure othe wiper against the cam rocks the forwardly extending arm oftheactuating lever downwardly against the teng slon of a restorlng spring480, andthe upwa'rdly extending arm 419w of the lever rocks forwardly.

r The wiper reaches the apex of the abrupt cam 419" shortly after themain drive shaft starts on its forward stroke and then rides down theforward face of the cam, thereby relieving its pressure on the cam, toenable the actuating lever to rise under the influence of its spring480, until it is arrested by contact with the cross rod 508 under whichthe lever passes or by a collar thereon. This results in imparting ashort snappy oscilla tion to the actuating lever, which returns tonormal position early in the forward stroke of the main drive shaft.

The wiper 354, upon its return stroke, which occurs coincidently withthe return of the main drive shaft, strikes the forward lower' edge ofthe cam 419e, which is interposed in the path of return of the wiper bythe restoration of the actuating lever, and raises the cam and thecarrier 419f5 against the tension of spring 480, which latter restoresthe carrier and cam to normal position, as soon as the wiper, travelingalong the lower fiat face of the cam, Clears the rear end of the latter.

It will be noted that the actuatin mechanism functions at each operationo the machine.

The actuating mechanism is adapted to operate a driving means, which, inthe present instance, includes a bent arm 419a (best shown in Fig. 3)journaled on, and extending upwardly from, the cross shaft 1801, whicharm supports a substantially triangular drive member 419' pivotallymounted on one of its angles, at 350 intermediate the ends of the arm419. A check lug 419t on the arm.l projects laterally in front of thevertical forward face of the triangular member 419, and a spring orflexible link 480*l yieldingly holds the triangular drive memer againstthe check lug. A weaker spring 480b connected to the supporting arm 419,normally holds the drive mechanism (in cluding the arm 419 and member419) in its rearward position against an arresting Stud 4615'.

' 'A cdupler-4l9, pivted at 350 to the bent supporting lever 419,relea'sably connects the' actuating and driving mechanisms. The coupler,in the present instance, is

stanttially U-shaped, one branch of the cow pler terminating* in a hookor 1i -419 adapted to' engage an ear 419v on t e 'upwardly extending arm419" ofv the actuating lever 419Jv the remaining branch of the' couplerhaving formed therein an arcuate slot 4119"nl to accommodate a stud 461pmounted on an arm 419"l extending rearwardly from one end of a bail 4193ourna1led: on a cross rod 903. The spring 480l connected to the bail,normally holds the rea/rwardl xtending arm 4I9S depressed and tlhelheoandina* of the coupler disengaged from the ear 419' on the actuatinglever, als 'shown in: Fig. 1.

To enable the operator' toeouple amd uncouplei the actuating and drivingmechanisms, at' will, provide the inner end of the bail 419 with aforwardly projecting arm 4191" (li'g', 3) carrying a stud 245k .enteredin' a slbtl irrthe stem! 419" el a' key492 (Figs. 1 and-2). A springlinlr 685 connects the stud' 2451-and key stem, and normally holds thekey elevated.

Depression( of the "key 492 tensionsv the spring 685 connected to the'fbrwardly proi jecting arm 4'19" of the bail 419, to turn the bailonthe'cross rod '903and swin its rearward'ly extending a-rrn 419qiupwardly.` The stud 461 ,nsnch rearwardry extending arm, travels towardthe outer end of the arcuate slot 419r in the upper branch of thecoupler 419', to'roek the lower branch ofthe coupler upwardly andinterpese the hook 419 into the pat 4 o'f the ear 419' of the actuatinglever 4195; The' actuating lever is thus enabled to draw the supportingarm 419 and driver 419 forwardly against the tension of the restoringspring 480". 'The arcuate slot in the upper ar'm' of the coupler 419i,conforms to the ath of travel of the coupler when operate by theactuating lever, to prevent disengagement of the coupler relatively tothe lever 4191, due to such travel.

The ,drive means may conveniently opcrate the' counter-selectionmechanism in t e following manner.

A

Turning the main drive shaft 200,--onits #Forward stroke, imparts'asnappy oscillation to the actuating mechanism at the out- -set of suchforward stroke, which oscillatory movement is communicated to theflexible drive mechanism through the coupler 419', to rock the latterincluding the drive member 419l forwardly against the tension vof therestoring spring 480.

The tappets 2018 and 2018c are located along the supporting bar 2092e insuchrelation to the usual tabulating stops (not herein shown) that, 'asthe carriage feeds from column to column, certain of the tabulatingstops which -arrest the 'carriage in position to permit printing in therespective columns, will also locate one or another of the i of work forwhich this mechanism is adaptedwill more clearly illustrate itsoperation.

It is often desired to list debits in one colg umn, and accumulatethemen. one setrof counters, to list credits in another column, andaccumulate them on a second serles of counters, `and to print adesignating gure,

' dateyitem, or what not in another column which is not to beaccumulated.

A convenient form and one which is frequently used, is as follows:

' N0.` Cost price.V Selling price. 4382 19. 71 22. 50 7186 43. 07 75. 809271 7. 92 18. 00.

'i In performingv this example, the carriage will first be .located sothat the usual tabulating stop which holds the carriage at the righthand end of its travel, will position the column in which designatinmembers not to be accumulated, are liste ,opposite the types 561. Insuch position, `the carriage will also locate one of the shorter tappets2018c in contact with the stud 354 on the intermediate lever 2029, asshown in Fig. 5, to hold the latter partway between its inner and outerlimits of throw, against the tension of the restoring spring 480.

Under such adjustment, the lever 2029e will have rocked the switch toe419h forwardly toturn the shaft 406 and raise the adjuster 419 from itslowest position (shown in Fig. l), which it occupies when none of thetappets are in contact with the stud 354, to its intermediate position(Fig. 3), and the adjuster will have located the impact faces 6 of thetransmittin feelers 419i, 419 in line with the rearmost s oulders 4, 4

Providing the counter-selecting heads 418m are at one or the other oftheir extreme limits of travel, the impact face 6 of one or the other ofthe feelers will lie within the path of its shoulder 4 or 4', While theremaining feeler lies in line with its shoulder 4 or 4', but justoutside its path. Upon starting to operate the machine, the control key492 being depressed, the actuating lever 419j will be rocked downwardlyagainst the tension of the spring 480, to advance the driving head 2idly through a part of its stroke, against the tension of theA spring480", and cause it to strike the impact face 6 of the nearest feeler, tothrust the latter forwardly' and shift the counter-selecting heads 418mto their intermediate position, wherein idlefqfeeler contacts@ itsapprgprliate .,drive shoulder, after which any further.traye1..ef thedrive memberr 419,l` .will @serve to .center the coimterseleetng.member. 41,8jnate .fmtermediate position. i ci ,1..`;

I If thecounter-selecting heads 418m, stood in their intermediate 'positions (asin Fig. 3) prior to the" operation of the machine, then the impact faces6 of 'the transmitting feelers would each lie just vat the end of theforward travel of the shoulders 4,` 4', and the latter wouldA merelyserve to confirm or insure the accurate locationof the counterselectingmembers 418 in such intermediate position. f As the paper carriageshifts to the next column, the shorter'tappet 2018 releases the stud354, whereupon the spring480 draws the adjuster 419 'to itslowest-position and forces the stud 354 further outwardly into the pathof the next succeeding tappet 2018, for instance-` I The depression ofthe adjuster 419 lowers the impact face 6 of the yupper-feeler419d intoline with the forward drive-'shoulder 3 (see Fig. 1) ,and the impactfacei 6 ofithe lower feeler 419 drops to a point below and out of thepath of the drive shoulder 44.

During this operation, the driving head2 will clear the lower feeler'419by reason of vthe displacement of the latter relatively to its shoulder3', but such lower feeler will be shifted rearwardly as thecounter-selecting heads travel forwardly, in position to beadjustedinto` theY path of"its"shulder 3" in case the next adjustment shouldlocate it in such position, in order .to partake of substantially theentire advance of the shoulf der 3', just as the upper'feeler 419d`partakes of substantially the entire travel of the drive shoulder 3 inthe operation just described.

During this operation of the machine, the cost price will be listedin'its appropriate column and registered in the'rear set'of counters490x, in the manner heretofore explained. Q

As the carriage feeds to the next column, it vbrings thelong tappet 2018into contact with the stud 354, to forcethe lever 2029e to the forwardend of its travel, which lever, in turn, lifts the adjuster419 from itslowest to its highest position, to raise the impact face (i of the upperfeeler 419d above and out of the path of the driver head 2, and tolocate theimpact face 6 of the lower 'celcr 419 directly in front of itsshoulder 3.

After the selling price is set up on the keyboard, the machine isoperated, and at the outset of its operation, the drive mechanismthrusts the lower feeler 419 forwardly to shift the counter-selectingmember 418 from oneextreme osition to the other, t0 restrain the formery operative counters in idle position, and to release the formerly idlecounters for operation. The sellin price will have been listed in itscolumn an registered in its set of counters 490 at the rrmclusion. ofthe operation of the machine.

(lf course, if it is desired at any time to repeatedly add amounts in asingle set of counters, but to enter such amounts in successive columns,all that is necessary is to either locate a correspondingr number oflong tappets 2018 in position to contact the stud 3:34 as the successivecolumns are brought to printing position, or else to omit lappots from aseries of corresponding col.- uiun positions, depending upon which setof counters are to be active. 0r, if items printed in successive columnsin cross tabulating` are to be non-added, a corresponding number ofshort tappets 2018c are located on the ha r 2092 in position tosuccessively control the lever 2029*, as the carriage brings thesuccessive columns to yprinting position.

Another method to which the operator might resort, :should he desire toretain the counter-selecting means against automatic operation, is tograsp and hold the handle 418? in the1 desired position torelease theproper counters for operation.

4 Theexercise `of such restraint on the handle, lwill result in causingthe impact face 6 or 6 of the particular feeler 4191 or 419 againstwhich the driving head2 impin es, to act as a check to prevent the compete advancepf the driving head# The throw of the supporting'arr 419,howeverQ'is iiot restricted, and'the latter will; rock fas usual againstthe tension of'theres'toring spring 480, and also 'against the tensionofthe fiexible link 480l which connects .the arm and the drivingmember419.,- I

The operator may shift thecounter-selecting members 418 to any of theirpositions by manipulating the handle 418|? regardless." of the positionsof the feeleisfl-LS, 419, or of the tappets 2018,iL 2018?, but itynlay'be rnecessary tojretain thewhandle manually in shifted, Vposition,during the first, partof'the operatlon of the machine,depending'npon'whether or not the adjusting mechanism is set to'effect adifferent positioning oftlie counterselecting)members, f i

f course, releasing the control key 492 severs the connection betweenthe actuating and drive mechanisms, by relaxing ,the tension of thespring 685 andfreeing'the bail 419h to the action of its spring'480,which rocks downwardly'the rear arm' 419q of the bail, and the` armswings the coupler 419t downwardly, to displace the hook 419" relativelyto the ear 419v on the actuating lever 4191, as shown in Fig. 1. Underthis adjustment the drive mechanism remains idle during operations ofthe machine.

bviously, the tappets 2018, 2018c may be arranged in any desiredsuccession to accommodate different forms.

Attention is also directed tothe fact that the tappets merely controlthe position of the adjusting and transmitting mechanism, through whichthe counter-selecting heads are shifted, the actual power to shift thecounter-selecting mechanism being derived from the main drive shaft ofthe machine.

In view of the fact that the automatic counter-selection takes placeafter the main drive shaft starts on its forward stroke, it is necessaryto disable the locks which prevent manual adjustment of thecounterselecting mechanism after the main drive shaft has started.

This I conveniently accom lish by providing a rearwardly extending link523d 'having at its forward end a loose pin and slot connection 264mwith the tail of the latch 423", and connected at its rear end to thelower arm of a bell crank lever 419 Y journaled on a stud 562. A shortlink 4201l connects the upper arm of the bell crank lever 419 with anarm 8 projecting forwardly Vfrom the coupler-controlling bail 419", theshort ylink 420El and upper arm of lever 419 forming a toggle mechanism.

l Depression ofthe key 492 rocks the bail 419", as heretofore explained,and lowers the forwardly' `projecting arm 8 to rock the lever v419 andthrust the link 523l forwardly. The link swings the latch 423drearwardly to restrain it in Aidle `position against the tension of itsdrive spring 289, so that when the restraining stud 259, on its advance,releasesthe latch, the latter cannot assume its effective position.

The pin and slot connection 264 between the -latch and link 523l permitsoperation ofl the latch relatively to the link when the controlkey 492is in elevated position.

Furthermore,the latch 423d carries a pin 254", which, when the latchswings rearwardly upon the depression of the control key y492, ridesalong a cam edge 420m terminating in a dwell portion, formed on the rearend of a disabling lever 420c pivoted on thestub shaft 457, to rock thelever 420. The forward end of the disabling lever has a \pin and slotconnection 253 with the link 423b extending between the oscillatorylever 422 and the dog 423, and when the pin 254b rocks fthe disablinglever 420, the latter draws the link 423" downwardly relatively to thelever 422 and displaces the dog 423 relatively 'to the full strokesegment 210.

When the control bail 419'J restores to normal position under theinfluence of the spring 480, upon the release of the key 492. the ar1n-8rises, drawing with it the link 420 to rock the bell crank 419 Yand.shift the link 523d to release the latch 423d for opration.

Since the counter-selecting mechanism operates during the first part ofthe forward stroke of the main drive shaft, and also since, in totalingand clearing operations, the counters are meshed with their racks atsubstantially the saine period in the operation of the machine, it isobvious that, to avoid conl'lict or interference between thecounter-selection, and the totaling and clearing operations, it isadvisable to disable the automatic counter-selectingr mechanism whentotaling or clearing operations are to beperformed, and thus preventinterruption of the operation of the machine, or injury thereto.

Therefore, I conveniently arrange to dis -able the coupler 419f upon thedepression of eithenthe total key 327h clearing :key 327.

In the before-mentioned Pentecost and Fisher application, filed July 17,1918, Serial No. 245.273,:1nd asshown in Fig. 1. the clearing and thetotal keys are provided i ,es t fers (Fig. l) or the.

with wiping studs 352 and 352m, res' ectively, adapted to ride alonginclines 26" and 326| of different lengths formed on the forward end ofa longitudinally extending thrust bar 326, which forward end liesbeneaththe total and Aclearing key stems. A crank 1,814 connects the rear endof the thrust 'bar fto the cross shaft 1801 on which is mounted means(not herein shown) to position different sign printing types (also notshown) at the printing line.

Depressionof `either key 327b or 327 'wil l turn the shaft 1801, theonly di'erence in this respect, being Vthat depression of the clearingkey 327, whose stud 352" rides along the shorter incline 326m, will turnthe shaft f 1801 lthrou h a lesser angle than will the total key 3 7b.

I conti-ive to utilize the shaft v1801 to disable the automaticcountecselecting mechanisrn, by mounting 'thereon ".atrijglpery 324d undprovidin` I the coupler-'controlling bail 419b with a ependig trigger-9.Depression of the control key 492,!which rocks the bail to set thecoupler tbfeflecti've position, swings the free end ofthedependingtrigger 9 to a int closely adjacent to or in contact with te tripper 324", (see 3).

With the trigger 9 in such position, depression of either the total orclearing keys swings the tripper 324i against'the trigger to press thelatter forwardly and rock the controlling bail' 419 against the 'tensionof spring 685, the stud 2451L'traveling upwardly in the slot 1 of thecontrolling key stem 419,`provided to permitthis operation. it beingremembered that the key stem remains locked in depressed position.

Such enforced rocking of the bail depresses its rearwardly projectingarm 419q carrying the operating stud 461 to cause the latter to swingthe u per branch of thicoupler 419t -downwar ly and displace the lip 419of the coupler from in front of the lug 419v on the shorter arm 419w ofthe actuating lever 4191. The actuating lever is thus prevented fromoperating the drive mechanism, and hence the counter-selecting mechanismis rendered inactive. irrespective of the position of thefeeler-adjusting mechanism and of the carriage, as well as the controlkey 492.

The controlling bail 419", when rocked by the tri per 324, operatesthrough the toggle link 4 lever 419, and connecting link 523i to releasethe latch 423'1 to the action ot its spring 289, which restores thelatch to normal position, thereby rendering the disabling .lever 420cineffective to hold the dog 423 inoperative.

At the conclusion of a totaling or clearing operation, the keys 327 b or327 rise to enable the draft link 3261 to return to normal position,thereby withdrawing the tripper 3241. whereupon spring 685 reverses theposition mausi-x15V 'riagemay be manually shifted, or may. be drawninone direction by the usual spring.

drum, and tripped automatically or by hand, to bring the successivetappetsto effective position. y l I Changes may be made in the form andarrangement of the several parts set forth;
